Esteqlal had to win its two remaining matches to keep alive its already faint hope of sweeping into the next round. However, the 1-1 home draw left Esteqlal at the bottom of Group C without a single victory out of its five matches.
Qalenoi resigned from his post after the match due to differences with the club's Chief Executive Amir Vaez-Ashtyani. His resignation comes a week after he won Iran's Premier League title with Esteqlal.
Hicham Aboucherouane scored the opener for Al-Ittihad after 80 minutes, eight minutes before Ali Alizadeh gave a brief relief to Esteqlal before 25,000 fans at Tehran's Azadi Stadium, press tv reported.
The victory sent Al-Ittihad to the top of the group with 9 points, 2 points ahead of Qatar's Umm-Salal, which will face UAE's Al Jazira later on Tuesday.
